Noticed this morning that when I turn off the engine on my 2003 Focus, the temperature and gasoline gauges continue moving, going up and down.
Even after 10 minutes it was still doing that. I checked the battery and alternator, all good.
What could be the issue?
Edit: I saw this link but it can't be humidity as the car never/barely sees rain. It started this morning out of nowhere.

Edit number 2: if I disconnect the battery negative cable, gauges stop moving.
